a little less than 20A through a “normal” fl ight. This is a
suitable propeller choice and fl ies the Uproar V2 well. Another
suitable propeller choice is the APC 14 x 7 which provides
slightly more thrust at the expense of a little speed. You can
experiment with different propeller choices in this range as
long as they do not exceed the amperage specifi cations of
the motor.
Typical fl ight time may be as low as 4 minutes or over 8
minutes depending on how aggressive and active you are
with the throttle – more throttle means shorter fl ight times.
In any case, use a fl ight timer initially set to a conservative
time (4 minutes for example). When the timer sounds, land.
Use a LiPo checker to measure the resting (unloaded) voltage
when you land. The voltage should not be below 3.75V/cell.
When you charge the battery also note how much capacity
it took to recharge (indicating how much was used for the
fl ight). Aim to use no more than 80% of the battery’s capacity.
Adjust your timer according to the voltage and capacity used
for the fl ight.
You can also use the worksheet on page 28 to determine
optimum flight times based on your flying style and
battery capacity.
CAUTION:
Never run the motor on the ground for more
than a few seconds. Otherwise, you may overload the
motor, battery or ESC.
Battery Precautions
Charge and store LiPo batteries in a safe place!
Never leave charging LiPo batteries unattended!
Before mounting the motor and setting up the ESC and
battery, read the following important battery precautions:
IMPORTANT:
If using multiple battery packs that are
connected with an adapter, never charge the batteries
together through the adapter. Always charge each
battery pack separately. Charge the batteries, then read
the following precautions on how to connect multiple
packs for fl ying the model:
Battery Precautions:
There are two ways to connect multiple battery packs: In
Series
and in
Parallel
.
This is a
SERIES
battery adapter
that connects two batteries in series.
(3-Cell) 3200 mAh
(2-Cell) 3200 mAh
11.1V
7.4V
These are two 3200mAh batteries (one 11.1V and the
other 7.4V). When joined in
SERIES
, the result will be a
18.5V, 3200 mAh battery.
1. Connecting batteries in
“Series”
means to connect the
+’s to the –’s and the –’s to the +’s. This combines the
batteries’ Voltages, but the capacity remains the same.
This is a
PARALLEL
battery adapter that
connects two batteries in parallel.
(3-Cell) 1500 mAh
(3-Cell) 1500 mAh

These two 1500mAh batteries (both 11.1V) are being
joined in
PARALLEL
. The result will be one
11.1V,
3000mAh
battery.
2. Connecting batteries in
“Parallel”
means to connect
the +’s to the +’s and the -’s to the -’s. This combines the
batteries’ capacities, but the Voltage remains the same.
